BACKGROUND 1. Field

The present disclosure relates in general to an electronic wallet function of an electronic device and, more particularly, to an electronic wallet function of an electronic device at the offline merchant to automatically connect to wireless fidelity (Wi-Fi) of the offline merchant.

2. Description of Related Art

Wireless local area network (WLAN) communication (Institute for Electrical and Electronics Engineers (IEEE) 802.11 standards), which is generally known as Wi-Fi, has continuously evolved in a complementary relationship with wireless mobile communication. Wi-Fi is a technology for providing an Internet access function to electronic devices located within a specified radius from a place where an access point (AP), that is, a wireless router, is installed and is used at home, office, school, airport, restaurant, or café.

Since Wi-Fi is free-of-charge unlike wireless mobile communication, commercial facilities, such as a hotel, a restaurant, or a cafe, provide a Wi-Fi service for the convenience of customers. Customers can use the Wi-Fi service by asking a staff member a Wi-Fi password or obtaining the password printed on a receipt and entering the obtained password directly into an electronic device.

However, the customer is inconvenienced by having to directly enter a Wi-Fi password into an electronic device in order to use the Wi-Fi service at conventional commercial facilities. If the Wi-Fi password is disclosed to a person other than the customer, the commercial facilities have no way of preventing the person from accessing Wi-Fi.

FIG. 5 is a flow diagram of a payment method using an electronic device according to an embodiment of the present disclosure. The embodiment illustrated in FIG. 5 shows an example in which when an electronic device 503 receives connection information for connecting to Wi-Fi, an entity that determines a condition for transmitting the connection information to the electronic device 503 is a POS terminal 502.

Referring to FIG. 5, in step 511, the electronic device 503 may receive a payment request from a user via a payment application program (or payment app) 504 and may transmit a payment signal to the POS terminal 502 in response to receiving the payment request. The payment signal may include ID information about the electronic device 503, account information about the payment app 504, the serial number (e.g., an international mobile equipment identity (IMEI)), a medium access control (MAC) address or payment information of the electronic device 503, and the like. The payment app 504 may generate payment information in response to the payment request. For example, the payment app 504 may determine a payment method (e.g., an electronic credit card) on the basis of a user input and may request user authentication (e.g., fingerprint authentication and iris authentication) to perform payment. The payment app 504 may obtain a payment token in response to the completion of user authentication and may generate payment information on the basis of the obtained payment token. The payment app 504 may obtain the payment token by requesting the payment token from an external device (e.g., the electronic wallet server 230 or the payment server 240). Alternatively, the payment app 504 may directly generate a payment token on the basis of an encrypted key stored in a memory 213 of the electronic device 503. For example, the payment app 504 may obtain the payment token through a program associated with a payment method (e.g., a credit card) selected by the user in response to the payment request from the user. For example, the payment app 504 may obtain the payment token through a program associated with a credit card selected by the user. The program may be installed in a trusted execution environment (TEE), such as TrustZone, or may be installed in an embedded secure element (ESE). The program may be a software development kit (SDK) program distributed by a credit card company.

The payment app 504 may transmit the generated payment information to the POS terminal 502 through a first near-distance wireless communication circuit 217 a. The first near-distance wireless communication circuit 217 a may be configured to support MST and/or NFC.

In step 512, the POS terminal 502 may perform payment approval in response to the payment request received from the electronic device 503. For example, the POS terminal 502 may transmit transaction information based on the payment request to a payment intermediary server (e.g., the VAN company 420), and the VAN company 420 may transmit the received transaction information to a relevant credit card company 430. The credit card company 430 may check the received transaction information and may then notify the POS terminal 502 of payment approval via the VAN company 420. The POS terminal 502 may determine a Wi-Fi connection condition in response to the payment approval. For example, the POS terminal 502 may determine credential information for connecting to a Wi-Fi AP 501 on the basis of a specified amount of money or the number of products sold. The credential information may include the number of devices allowed to connect to the Wi-Fi AP 501 and connection time. The POS terminal 502 may request the Wi-Fi AP 501 to generate a Wi-Fi connection token on the basis of the determined credential information.

In step 513, the Wi-Fi AP 501 may generate a Wi-Fi connection token that matches the credential information in response to the Wi-Fi token generation request received from the POS terminal 502 and may transmit the generated Wi-Fi connection token to the POS terminal 502. The Wi-Fi connection token may include an SSID for connecting to the Wi-Fi AP 501, an encrypted key, or a usage period.

In step 514, upon receiving the Wi-Fi connection token from the Wi-Fi AP 501, the POS terminal 502 may generate receipt information and Wi-Fi connection information and may transmit the generated receipt information and Wi-Fi connection information to the electronic device 503. The POS terminal 502 may encrypt the Wi-Fi connection token on the basis of the ID information about the electronic device 503 previously received from the electronic device 503 and may transmit the encrypted Wi-Fi connection token as the Wi-Fi connection information.

In step 515, upon receiving the receipt information and the Wi-Fi connection information from the POS terminal 502, the payment app 504 may automatically perform a connection to the Wi-Fi AP 501. For example, the payment app 504 may decrypt the Wi-Fi connection token on the basis of the ID information about the electronic device 503 and may transmit the decrypted value (or information) to a Wi-Fi module 505 (e.g., the second near-distance wireless communication circuit 217 b) of the electronic device 503. The Wi-Fi module 505 of the electronic device 503 may perform a connection to the Wi-Fi AP 501 on the basis of the Wi-Fi connection token.

The Wi-Fi connection token may not be separately specified as a method for distinguishing and authenticating the electronic device 503. For example, the Wi-Fi AP 501 may authenticate the electronic device 503 requesting a connection by comparing ID information about the electronic device 503 requesting the connection with previously stored ID information about the electronic device 503. For example, the electronic device 503 may transmit a payment request to the POS terminal 502, and the POS terminal 502 may transmit the ID information about the electronic device 503 to the Wi-Fi AP 501 in response to the payment request. The Wi-Fi AP 501 may store the ID information about the electronic device 503 received from the POS terminal 502, and may receive a connection request from the electronic device 503 after storing the ID information about the electronic device 503. Upon receiving the connection request from the electronic device 503, the Wi-Fi AP 501 may compare the ID information about the electronic device 503 requesting the connection with the previously stored ID information about the electronic device 503 and may allow the connection of the electronic device 503 if the ID information about the electronic device 503 requesting the connection is the same as the previously stored ID information about the electronic device 503.

FIG. 6 is a flowchart of a method of an electronic device according to an embodiment of the present disclosure. FIG. 6 shows an example in which an external server 230 transmits Wi-Fi connection information to an electronic device 210.

Referring to FIG. 6, in step 601, the electronic device 210 may receive a request associated with a payment and may perform a transaction with a POS terminal 221 via a first near-distance wireless communication circuit 217 a in response to the request.

In step 603, the electronic device 210 may receive the result of the transaction including receipt information and connection information from an external server 230 through a cellular wireless communication circuit 217 c. The connection information may be configured such that the POS terminal 221 transmits Wi-Fi connection information to the external server 230 after receiving a payment request from the electronic device 201 and the external server 230 transmits the Wi-Fi connection information received from the POS terminal 221 to the electronic device 210. An embodiment is described below in greater detail with reference to FIG. 7. The connection information may be configured such that Wi-Fi connection information about a merchant is shared in advance with the external server 230 before the electronic device 210 transmits a payment request, and the external server 230 transmits the Wi-Fi connection information shared with the merchant to the electronic device 210 when a payment is made through the electronic device 210. An embodiment is described below in greater detail with reference to FIG. 8.

In step 605, after receiving the result of the transaction including the receipt information and the connection information, the electronic device 210 may connect to a Wi-Fi AP 222 of the merchant through a second near-distance wireless communication circuit 217 b on the basis of credential information included in the connection information.

FIG. 7 is a flow diagram of a payment method using an electronic device 701 according to an embodiment of the present disclosure. FIG. 7 shows an example in which a POS terminal 702 transmits Wi-Fi connection information to a credit card company server 703, the credit card company server 703 transmits the received Wi-Fi connection information to an electronic wallet server 704230, and the electronic wallet server 704 transmits the Wi-Fi connection information to the electronic device 701 through a push server 705.

Referring to FIG. 7, in step 711, the electronic device 701 may receive a payment request from a user via a payment app 504 and may transmit a payment signal to the POS terminal 702 in response to the received payment request. The payment signal may include ID information or payment information about the electronic device 701. The electronic device 701 may generate the payment information using the payment app 504 to in response to the payment request. For example, the payment app 504 may determine a payment method (e.g., an electronic credit card) on the basis of a user input and may request user authentication (e.g., fingerprint authentication and iris authentication) to perform payment. The payment app 504 may obtain a payment token in response to the completion of user authentication and may generate payment information on the basis of the obtained payment token. The payment app 504 may request the electronic wallet server 704 to issue the payment token and may obtain the payment token from the electronic wallet server 704. The payment app 504 may request the credit card company server 703 to issue the payment token and may obtain the payment token from the card company server 703. Alternatively, the payment app 504 may directly generate a payment token on the basis of an encrypted key stored in a memory 213 of the electronic device 701. The payment app 504 may transmit the generated payment information to the POS terminal 702 through a first near-distance wireless communication circuit 217 a. The first near-distance wireless communication circuit 217 a may be configured to support MST and/or NFC.

In step 712, the POS terminal 702 may determine credential information for connecting to a Wi-Fi AP 222 on the basis of a specified amount of money or the number of products sold in response to the payment request received from the electronic device 701 and may generate and encrypt Wi-Fi connection information (e.g., the Wi-Fi connection token in FIG. 5) on the basis of the determined credential information. The POS terminal 702 may include a token generation module that generates a Wi-Fi connection token that matches credential information in response to a payment request received from the electronic device 701. The Wi-Fi connection token may include an SSID for connecting to the Wi-Fi AP 501, an encrypted key, or a usage period.

In step 713, the POS terminal 702 may transmit the payment information and the encrypted Wi-Fi connection information based on the payment request to the credit card company server 703 via a payment intermediary server (e.g., the VAN company 420).

In step 714, the credit card company server 703 may check received transaction information, notify the electronic wallet server 704 of payment approval, and transmit the Wi-Fi connection information to the electronic wallet server 704.

In step 715, the electronic wallet server 704 may request the push server 705 to forward a notification of payment approval and the Wi-Fi connection information in the form of a push message. In step 716, the push server 705 may notify the electronic device 701 of the payment approval and may transmit the Wi-Fi connection information to the electronic device 701 in response to the push request from the electronic wallet server 704.

Upon receiving the Wi-Fi connection information from the push server 705 using the payment app 504, the electronic device 701 may automatically connect to the Wi-Fi AP 222 in step 717. For example, the payment app 504 may decrypt the Wi-Fi connection token on the basis of the ID information about the electronic device 701. After decrypting the Wi-Fi connection token, in step 718, the electronic device 701 may request user consent (user confirmation) and may perform a connection to the Wi-Fi AP 222 on the basis of the Wi-Fi connection token via a second near-distance wireless communication circuit 217 b of the electronic device 701. After decrypting the Wi-Fi connection token, in step 718, the electronic device 701 may automatically perform a connection to the Wi-Fi AP 222 on the basis of the Wi-Fi connection token via the second near-distance wireless communication circuit 217 b of the electronic device 701 without requesting user consent (user confirmation).

FIG. 8 is a flow diagram of a payment method using an electronic device according to an embodiment of the present disclosure. FIG. 8 shows an example in which Wi-Fi connection information about a merchant is shared in advance with an external server 230 before an electronic device 210 transmits a payment request, and the external server 230 transmits the Wi-Fi connection information shared with the merchant to the electronic device when payment is performed through the electronic device 210.

Referring to FIG. 8, in step 811, a merchant 801 may register connection information about a Wi-Fi AP 802 in advance in an electronic wallet server 807. For example, a manager of the merchant 801 may connect to the electronic wallet server 807 through a merchant server or through a website linked to the electronic wallet server 807 and may register an SSI© for connecting to the Wi-Fi AP 802, an encrypted key, or a usage period as the connection information about the Wi-Fi AP 802 of the merchant.

In step 812, the electronic device 804 may receive a payment request from a user via a payment app 805 and may generate payment information in response to the received payment request. For example, the payment application 805 may determine a payment method (e.g., an electronic credit card) on the basis of a user input and may request user authentication (e.g., fingerprint authentication and iris authentication) to perform payment. The payment app 805 may request a payment token from the electronic wallet server 807 in response to the completion of user authentication.

In step 813, the electronic wallet server 807 may forward a payment token request received from electronic device 804 to a credit card company server 808. In step 814, the electronic wallet server 807 may obtain a payment token from the credit card company server 808. In step 815, the electronic wallet server 807 may transmit the payment token obtained from the credit card company server 808 to the electronic device 804. Alternatively, the electronic device 804 may directly generate a payment token using the payment app 805 on the basis of an encrypted key stored in a memory 213 of the electronic device 804.

The payment app 805 may generate payment information on the basis of the obtained payment token. In step 816, the payment app 805 may transmit the generated payment information to a POS terminal 803 via a first near-distance wireless communication circuit 217 a, The first near-distance wireless communication circuit 217 a may be configured to support MST and/or NFC.

In step 817, the POS terminal 803 may transmit the payment information based on the payment request received from the electronic device 804 to the credit card company server 808 via a payment intermediary server (e.g., the VAN company 420).

In step 818, the card company server 808 may check received transaction information and may notify the electronic wallet server 807 of payment approval.

In step 819, the electronic wallet server 807 may determine credential information for connecting to the Wi-Fi AP 802 on the basis of a specified amount of money or the number of products sold. The electronic wallet server 807 may generate Wi-Fi connection information (e.g., an SSID, an encrypted key, or a usage period) to include the determined credential information using the encrypted key registered (shared) in advance by the merchant 801 as the connection information about the Wi-Fi AP 802 and may encrypt at least some (e.g., the encrypted key or usage period) of the generated connection information. The electronic wallet server 807 may notify the electronic device 804 of payment approval and may transmit the generated Wi-Fi connection information to the electronic device 804.

In step 820, upon receiving receipt information and the Wi-Fi connection information from the electronic wallet server 807, the payment app 805 may automatically perform a connection to the Wi-Fi AP 802. For example, the payment app 805 may transmit data encrypted with information related to a connection condition, such as the Wi-Fi connection information received from the electronic wallet server 807, for example, the SSID, the encrypted key, or the usage period, to a Wi-Fi module 806 (e.g., the second near-distance wireless communication circuit 217 b), thereby requesting the Wi-Fi module 805 to connect to the Wi-Fi AP 802. In step 821, the Wi-Fi module 806 of the electronic device 804 may attempt to connect to the Wi-Fi AP 802 by transmitting the encrypted data to the Wi-Fi AP 802. The Wi-Fi AP 802 may decrypt the encrypted key received from the Wi-Fi module 806 of the electronic device 804 and may determine whether to allow the connection of the electronic device 804 on the basis of the decrypted encrypted key. The Wi-Fi AP 802 may determine whether to allow the connection of the electronic device 804 on the basis of additional information, for example, a usage period and an allowed number of devices, received from the Wi-Fi module 806 of the electronic device 804.

FIG. 9 is a flowchart of a method of an electronic device configured to set a period of connection to a Wi-Fi AP.

Referring to FIG. 9, an electronic device 210 has a period of connection to a Wi-Fi AP 222 set to automatically expire.

In step 901, the electronic device 210 may receive a request associated with a payment and may perform a transaction with a POS terminal 221 through a first near-distance wireless communication circuit 217 a using a payment app 504 in response to the request.

In step 902, the electronic device 210 may receive the result of the transaction including receipt information and connection information from an electronic wallet server 230 through a cellular wireless communication circuit 217 c. The electronic device 210 may perform payment using an NFC method. For example, when the electronic device 210 performs payment using the NEC method, the electronic device 210 may receive the connection information for connecting to the Wi-Fi AP 222 from the POS terminal 221 through NFC communication. The connection information received from the electronic wallet server 230 may include an SSID for connecting to a Wi-Fi AP 222, an encrypted key, or a usage period. The usage period may include a service start time and a service expiration time.

In step 903, the electronic device 210 may automatically connect to the Wi-Fi AP 222 on the basis of the connection information and may register the usage period (connection period) of the Wi-Fi AP 222 in a timer on the basis of received period information. For example, the payment app 504 of the electronic device 210 may generate a timer task on the basis of the received period information and may transmit the timer task to a Wi-Fi module 1005.

In steps 904, 905, and 906, the electronic device 210 may operate the registered timer and may release the timer when the service usage period expires. For example, when the period information received from the electronic wallet server 230 is two hours, the electronic device 210 may operate the timer set to two hours. When the set period of the timer, for example, two hours, elapses, the electronic device 210 may release the timer.

In steps 907 and 908, the electronic device 210 may determine whether the electronic device 210 is connected to the Wi-Fi AP 222 of the merchant as Wi-Fi with advanced security even after the expiration of the timer, and may disconnect from the Wi-Fi AP 222 and may display a notification indicating the expiration of the Wi-Fi service if the electronic device 210 is connected to the Wi-Fi AP 222.

FIG. 10 is a flow diagram of an electronic device 1002 having a period of connection to a Wi-Fi AP set to automatically expire.

Referring to FIG. 10, in step 1011, the electronic device 1002 may perform a transaction with a POS terminal 221 through a first near-distance wireless communication circuit 217 a using a payment app 1003 and may receive the result of the transaction including receipt information and connection information from an electronic wallet server 1001 through a cellular wireless communication circuit 217 c. The electronic device 1002 may perform payment using an NFC method. For example, when the electronic device 1002 performs payment using the NFC method, the electronic device 1002 may receive the connection information for connecting to the Wi-Fi AP 222 from the POS terminal 221 through NFC communication. The connection information received from the electronic wallet server 230 may include an SSID for connecting to a Wi-Fi AP 222, an encrypted key, or a usage period. The usage period may include a service start time and a service expiration time.

In step 1012, the payment app 1003 of the electronic device 1002 may generate a timer task on the basis of the received period information and may transmit the timer task to a Wi-Fi module 1005. The Wi-Fi module 1005 of the electronic device 1002 may operate a timer on the basis of the received timer task, and may release the timer when the service usage period expires. For example, when the period information received from the electronic wallet server 1001 is two hours, the Wi-Fi module 1005 may operate the timer set to two hours. When the set period of the timer, for example, two hours, elapses, the Wi-Fi module 1005 may release the timer.

In step 1013, the electronic device 1002 may determine whether the electronic device 1002 is connected to the Wi-Fi AP 222 of a merchant as Wi-Fi with advanced security after the expiration of the timer. For example, when the timer expires, the Wi-Fi module 1005 may disconnect from the Wi-Fi AP 222 and may notify the payment app 1003 that the Wi-Fi module 1005 is disconnected from the Wi-Fi AP 222. Upon receiving disconnection information, the payment app 1003 may display a notification indicating that the use of the advanced-security Wi-Fi service has expired.
